Effect of ferrostatin-1 and liproxstatin-1 during TNF-induced HT-29 cells apoptosis

Project description:Ulcerative colitis (UC) is an inflammatory disease characterized by an uncontrolled inflammatory response. Previous study showed that the immunological impairment elicted the alteration of inflammatory mediators, and ferroptosis was implicated with the lethal accumulation of reactive oxygen species (ROS).We have already found that lipid ROS level was elevated in both murine DSS colitis model and TNF-a-induced cell apoptosis model in vitro.Then we here use two ferroptosis inhibitors ferrostatin-1 and liproxstatin-1 trying to eliminate lipid ROS in order to relive the symptoms of colitis.But we strikingly notice that liproxstatin-1 could increase TNF-induced cell apoptosis instead of protecting cells from death as we expected before while the other inhibitor ferrostatin-1 could protect cells from death indeed.To evaluate the underlying mechanism, we performed the experiment using high-throughput sequencing and get data to explain the reason why liproxstatin-1 could increase TNF-induced cell apoptosis .

Effect of 4-HDHA during TNF-induced HT-29 cells apoptosis

Project description:Ulcerative colitis (UC) is an inflammatory disease characterized by an uncontrolled inflammatory response. Previous study showed that the immunological impairment elicted the alteration of inflammatory mediators, and ferroptosis was implicated with the lethal accumulation of reactive oxygen species (ROS).We performed lipidomics sequencing of TNF-a treated cell line mimicking the colitis in vivo.Surprisingly, we found that 4-HDHA,an autoxidation product of docosahexaenoic acid (DHA),had anti-apoptosis effect on colon epithelial cell line.To evaluate the underlying mechanism of the specific lipid perioxidin’s anti-apoptosis effect, we performed the experiment using high-throughput sequencing and get data to explain the reason why 4-HDHA could decrease TNF-induced cell apoptosis.

Effect of sodium butyrate on colorectal cancer cell line HT-29

Project description:Analysis of colorectal cancer (CRC) cell line HT-29 treated with Sodium Butyrate. Sodium Butyrate, a HDAC inhibitor present in gut, can differentiate the undifferentiated HT-29 to enterocytes by the induction of brush border enzyme alkaline phosphatase. Results provide the transcriptional profiling underlying the butyrate-induced differentiation of CRC.

Folic Acid study in HT-29 cells

Project description:Low intracellular folate levels diminish the growth rate of HT-29 human colon cancer cells. This is accompanied by a metabolic shift from cytosolic glycolysis towards mitochondrial oxidative phosphorylation, as demonstrated by a lower lactate production and an increased mitochondrial oxygen consumption rate. To obtain insight in the molecular effects underlying these changes, the steady state gene expression profiles of HT-29 cells with different intracellular folate concentrations were compared. The gene expression profile of HT-29 cells with low intracellular folate levels (grown for 3 weeks in 10 ng/ml folic acid (PGA)) was clearly distinct from that of the other exposure conditions, which provide sufficient intracellular folate levels (100 ng/ml PGA, 10 ng/ml methyltetrahydrofolate (MTHF) or 100 ng/ml MTHF). Intracellular folate deficiency, contrary to expectation, did not lead to major changes in expression of genes involved in energy metabolism. This suggests that the shift towards mitochondrial oxidative phosphorylation is not mediated at the transcription level. Furthermore, only minor changes in the expression of folate metabolism related genes were observed. The changes that were observed were consistent with nucleotide salvage and in agreement with nucleotide need of the slow-growing folate-deficient HT-29 cells. The major observed effects were on cell cycle related gene expression, which was increased and interferon-responsive gene expression, which was reduced. The increase in cell cycle related gene expression seems compensatory to the reduced cell growth. Down-regulation of the interferon-response may be explained by decreased expression of signal transducer and activator of transcription 1 upon folate deficiency.
